An exploratory study of activity in veterans with Parkinson's disease.

Movement disorder specialists have limited information on the specifics of how patients with Parkinson's disease (PD) spend their time. We deemed it important to examine the relationships among activity and daily energy expenditure (DEE), non-motor symptoms, and body mass index in veterans with PD who were outpatients at a Veterans Affairs medical center. In this exploratory study, we mailed demographic and activity questionnaires and gathered data on 100 patients. Activity was categorized into five domains and three intensity levels, and DEE was measured in kilocalories. Light activities accounted for 64.9% of DEE (9.1 h), moderate activities for 32.9% (2.1 h), and vigorous activities for 2.2% (0.1 h) of DEE. Television viewing comprised 10.6% (2.5 h) of the day. The effects of non-motor symptoms were significantly associated with more time spent on activities of daily life (ADL). Patients rated fatigue and pain as having the greatest impact on their daily activities. The overweight/obese group of PD patients expended more overall DEE (p = 0.044) and more DEE on social activities (p = 0.024) and light intensity activities (p = 0.021) than did the underweight/normal group. Leisure activities for both groups changed from active to passive. Veterans with PD primarily expended DEE on ADL, TV viewing, and light intensity activities. Television viewing time may have been under reported. Movement disorder specialists can be more proactive in referring patients to physical therapy and encouraging their participation in community exercise and support groups.

Assessment of appropriate medication administration for hospitalized patients with Parkinson's disease.

BACKGROUND: For Parkinson's disease (PD) patients, adherence to a regular PD medication schedule is important in achieving optimal symptom control. There are few published studies quantifying PD medication administrations in hospitalized PD patients. METHODS: Hospitalization records for 100 veterans with idiopathic PD and admitted to our center were reviewed to determine the on time rate and contraindicated medication doses. A barcode based computerized medication administration system within the electronic medical record provided information of the exact time the medication was given to a patient. RESULTS: Eighty-nine idiopathic PD patients met study inclusion criteria. Among them, 87 were on levodopa monotherapy or in combination with other PD medications. Two patients were on dopamine agonists only. A total of 3873 doses of PD medications were prescribed during hospitalization. Among 675 incorrect medication administrations, 322 doses were omitted, 300 doses late by ≥ 30 min, and 53 doses given early by ≥ 30 min. Contraindicated medications were prescribed for 19 patients. The correct administration percentage was lower during the first 2 days post-admission compared to subsequent days (mean 74.6% vs. 82.8%) and higher for patients who had neurological consultations (mean 85.5% vs. 76.5%). Correct administration rates were better for patient-based medication schedules (85.6%) than with hospital-based schedules (77.5%), but did not achieve statistical significance. CONCLUSION: Adherence to regular PD medication dosing schedules during hospitalization is problematic, but improves with specialist consultation. Staff involved in the admission process for PD patients should work to safeguard against disruption of the prescribed home dosing schedule.

Proxy reports in Parkinson's disease: caregiver and patient self-reports of quality of life and physical activity.

We evaluated patient-proxy agreement in a population of veterans with Parkinson's disease and compared levels of agreement by patient subgroups. Patient and caregiver pairs completed questionnaires composed of standard measures and additional demographic and activity questions. Participants completed the Center for Epidemiologic Studies Depression Scale (CES-D), the PD Questionnaire 39 (PDQ-39), and three questions regarding physical activity. Caregivers completed proxy forms of the PDQ-39 and the physical activity questionnaire. The proxy forms asked caregivers to choose the answers that best described their "friend's/patient's situation." The results of our comparison of patient and proxy reports of quality of life were consistent with findings in other diseases. On average, proxies rated patient disability higher and quality of life lower than did patients. However, our comparison of patient and proxy reports of frequency of exercise diverged from previously published work. Less agreement was observed between patient and proxy reports of physical activity, even though this is a more objective variable than are the domains measured by the PDQ-39. Proxy reports may diverge appreciably from patient self-reports. These differences should be considered in research design and clinical decision making. Alternative approaches to the measurement of patient relevant outcomes could supplement traditional, retrospective self-reports.

Major stressors facing patients with amyotrophic lateral sclerosis (ALS): a survey to identify their concerns and to compare with those of their caregivers.

OBJECTIVE: To identify and compare the primary existential, physical, and psychosocial stressors affecting patients with ALS and their caregivers. Health care providers, together with patients and their caregivers, are challenged to identify both physical and psychosocial concerns that have the greatest impact on quality of life over the course of a serious illness. It is also helpful to understand the priorities of these concerns from the patients' and caregivers' perspectives so that we can render optimal care and help patients and their families with the myriad problems that accompany a progressive and fatal disease. METHODS: We analyzed responses from the first 66 patients with ALS and 61 ALS caregivers who attended the Baylor College of Medicine, Department of Neurology, Vicki Appel MDA ALS Clinic and who completed our internally generated 19-item survey. Subjects were asked to choose their three most important concerns. For analysis purposes we categorized the data into three domains: existential, physical, and psychosocial. Demographic data were collected. The Appel ALS Rating Scale (AALS) was used to measure disease symptom severity. RESULTS: Sixty-six patients (45 men, 21 women) with a mean age of 57.9 (range 30-82) years and 61 caregivers completed the checklist. At the time the patients completed the survey, their mean AALS total score was 77.0 (range 34-132), indicating mild to moderate disability. The most important stressors identified by patients and caregivers were existential concerns (86.4% of patients and 79.7% of caregivers) and physical stressors (80.3% of patients and 76.3% of caregivers). Less than 50% of both groups endorsed psychosocial stressors (38%). However, when we analyzed the domain specific items, there was a significant difference between patients and caregivers on worries about the patient's dependency (37.9% of patients and 6.8% of caregivers). DISCUSSION: Health care professionals should apply a holistic approach to treatment and care of patients with ALS. Families should be included in the process, and it should not be assumed that patients and caregivers will agree on all issues. Future research should focus on therapeutic interventions to help ALS patients and their families cope with the multiple stressors accompanying a catastrophic illness.

A study comparing patients with amyotrophic lateral sclerosis and their caregivers on measures of quality of life, depression, and their attitudes toward treatment options.

OBJECTIVE: To compare amyotrophic lateral sclerosis (ALS) patients and their caregivers on measures of quality of life (QOL), depression, and their attitudes toward treatment options. METHODS: Over a 14-month period, we analyzed responses from 27 ALS patients and 19 ALS caregivers as they arrived at the Department of Neurology, Baylor College of Medicine, Vicki Appel MDA, ALS Clinic, and those who completed the study measures. Patients were given the Appel ALS Rating Scale (AALS), the ALS Functional Rating Scale (ALSFRS), McGill Quality of Life Questionnaire Single-Item Scale (MQOL-SIS), and the Beck Depression Inventory-II (BDI-II). An internally generated scale of 1-7 was used to measure perception of emotional support, QOL for others (i.e., the patient's perception of the caregiver's QOL and the caregiver's perception of the patient's QOL), and experience of pain. Attitudes toward treatment options were assessed by yes/no/uncertain responses. Caregivers were administered all of the above measures except the AALS, ALSFRS, and pain scale. Percentage, mean, and standard deviation values were determined. Significance levels were also calculated. RESULTS: Twenty-seven patients with a mean age of 57.2 (range 34-81) years and nineteen caregivers with a mean age of 56.9 (range 28-82) years completed the study. The patients were of moderate disease severity with a mean AALS total score of 76.3 (range 39-134) and a mean ALSFRS score of 28.4 (range 12-40). The mean rating of QOL for patients was 5.9 and the mean rating of QOL for caregivers was 5.7 (range 1-7). The patients reported slightly less depression (9.8) than their caregivers (10.7) (range 0-63). There was, however, no significant difference between patients and caregivers on scores of QOL and depression. Patients tended to overestimate caregivers' QOL by a small degree, whereas caregivers tended to underestimate the patients' QOL by a greater degree. Over one-half of both groups would consider percutaneous esophageal gastrostomy (PEG) placement. Patient and caregiver responses to the use of BIPAP differed. Though over half of both groups endorsed the idea of future BIPAP use, more patients (41%) than caregivers (5%) were uncertain. Only 3% of patients responded negatively compared to 32% of caregivers. Both groups were only minimally interested in future invasive ventilation. DISCUSSION: Factors contributing to quality of life, depression, and attitudes toward treatment options need to be periodically explored with patients and caregivers throughout the course of the illness. Health care professionals should recognize that the needs and goals of the two groups might differ. For both patients and caregivers, health care professionals should provide education and opportunities for discussion centered on the issues followed by referrals and interventions appropriate to the situation.
